Therefore, it is actually very helpful to use this kind of usb humidifier to humidify when using a computer. So how to buy a better USB humidifier?

　　Below are the tips.

　　First, we must try our best to choose some big brand products, and the after-sales service outlets of the big brands are in place. Some small manufacturers only sell products regardless of after-sales maintenance and other services, or there are very few maintenance service outlets, which cannot effectively guarantee the timeliness of the service.

　　Second, when buying a computer humidifier, do not be induced by the sales staff of some manufacturers. You must look at the internal structure of the product, for example, the setting of a fan. Products without a fan cannot be called a professional computer humidifier, Whether the machine manufacturing materials are healthy and environmentally friendly, etc.

　　Third, the plastic used in the housing of the computer humidifier is also very important. In order to reduce product costs, some manufacturers use secondary processed plastics, which have poor texture and pollution problems. As a computer humidifier to improve indoor air quality, if the more polluting plastic is used, it runs counter to the original intention of the product, and the degree of harm may be far greater than the positive effect of the product itself.

　　Finally, when the computer humidifier is running, it will produce a certain amount of noise. The noise itself is also a kind of auditory pollution. If the noise is too large, it will affect normal sleep and rest. High-quality computer humidifiers have relatively low noise. You can use the trial method to compare at the time of purchase.
